    摘要： The invention relates to a method for making a cylindrical bore into a conical bore using a honing tool, wherein the honing tool comprises honing stones (13), the length thereof being less than 1/2 the length of the bore to be processed, comprising the following steps: applying the honing stones (13) of the honing tool to the bore; honing the bore over its entire length with a maximum stroke (HMax= OP1 - UP); honing the bore with decreasing stroke (H), wherein a lower reversal point (UP) of the honing tool remains essentially unchanged; and ending the honing process as soon as the upper reversal point (OP) has reached a predefined end value (OP2). In another embodiment, the widening of the bore into a conical shape is carried out by controlling the feed force (Z) with which the honing stones (13) are pressed against the bore according to a position of the honing tool in the bore.

    摘要： The invention relates to a device and a method for producing a non-cylindrical inner surface (10) of a bore (4) comprising machining tools (9) which are arranged along the circumference of the bore (4) and can be radially advanced towards the inner surface (10) of the bore (4). The device comprises a primary advancing system (14) which comprises an axially movable advancing rod (13) for actuating the machining tools (9), thus exerting a primary force (F
    Z ) onto at least one machining tool (9), the at least one machining tool (9) being radially advanceable towards the bore (4) by means of said primary force. The primary force (F
    Z ) is dynamically superimposed with a secondary force which is generated by a secondary advancing system (16) that forms an integral unit together with the primary advancing system (14) or can be constructed in a modular manner. The secondary advancing system (16) is activated dependent on a current rotational movement and/or a stroke movement of the primary advancing system (14), a current tool position, or a specified advancing force, or the secondary advancing system is activated at a specified time. In the process, the tool is already widened by the primary advancement.
